【Python】唯品会购买商品

操作过程：唯品会进入之后，搜索商品，浏览网页，略掉不能选择的尺寸，选择之后，点击商品选择数量的加号，然后加入购物车。

实现代码如下：

 # coding=utf-8
 from selenium import webdriver
 from time import sleep
 import keyword
 from selenium.webdriver.common.keys import Keys
 from selenium.webdriver.support.wait import WebDriverWait
 from selenium.webdriver.support.ui import Select
 import csv
 import random
 import io

 # 滚动滚动条`
 def MoveScorllBar(driver, down, range1, range2):
     moneCount = random.randint(range1, range2)
     for num in range(1, moneCount):
         if (down == "down"):
             driver.find_element_by_xpath("//body").send_keys(Keys.DOWN)
             sleep(random.uniform(0.1, 0.5))
         else:
             driver.find_element_by_xpath("//body").send_keys(Keys.UP)
             sleep(random.uniform(0.1, 0.5))
     return

 # 弹出新的浏览器窗口后，将之后的操作指向新的浏览器窗口
 def SwitchWindow():
     windows = driver.window_handles
     driver.switch_to_window(windows[1])

 if __name__ == "__main__":

     #设置全局变量
     a = '耐克Nike AIR JORDAN 1 MID 男子白色配银灰色篮球鞋'
     num = ''
     datas=[]

     #打开浏览器，进入网站
     driver = webdriver.Chrome()
     driver.get("https://www.vip.com")
     MoveScorllBar(driver, "down", 10, 30)
     MoveScorllBar(driver, "up", 10, 30)

     #输入想要搜索的商品-->点击搜索按钮
     driver.find_element_by_xpath("// *[ @ id = 'J-search'] / div[1] / input").send_keys(a)
     driver.find_element_by_xpath("// *[ @ id = 'J-search'] / div[1] / a / span").click()

     # 进入商品详情页面
     driver.find_element_by_css_selector('section#J_searchCatList div:nth-child(2)').click()
     SwitchWindow()
     MoveScorllBar(driver, "down", 10, 30)
     MoveScorllBar(driver, "up", 10, 30)

     #统计页面上有多少个尺寸
     lists=driver.find_element_by_xpath("//*[@id='J-sizeArea-wrap']/dd[2]/ul").find_elements_by_tag_name('li')
     print(lists)
     for list in lists:
         a=list.get_attribute("class")
         sizes = list.get_attribute("data-size-name")
         #print(a)
         if "disabled" in a:
             print('这是个无效的的尺寸：%s' % sizes)
         elif "selected" in a:
             print('这是个已默认选择的或有机会的尺寸：%s' % sizes)

         else: #取上面if,elif外的其他所有情况
             if sizes != None:
                 print('已选尺寸：%s' % sizes)
                 list.click()
                 break
 #由于选中尺寸之后，鼠标停在尺寸上会弹出来一个tip框，挡上了下面的选择数量的加号按钮，所以没办法click上加好，所以之后我们再次浏览商品，让鼠标立刻开尺寸处，露出下面的数量选择的加号按钮。
     MoveScorllBar(driver, "down", 10, 30)
     MoveScorllBar(driver, "up", 10, 30)
     #选择数量
     addbutton=driver.find_element_by_xpath("//*[@id='J-num-select']/dd[1]/a[2]")
     print(addbutton)
     addbutton.click()
     sleep(3)
     # 加入购物车
     driver.find_element_by_class_name("ui-btn-loading-before").click()
     print('主人，您购买的商品已经加入购物车了，快去付款吧~')
     #driver.find_element_by_xpath("//*[@id='J-cartAdd-sizeID-1612349898']").click()
     #driver.find_element_by_class_name("vipFont num-add J-num-act-add").click()
